Note that it comes in  a discrete green colour.  Not the crowd attracting white of Canon L lenses.

A friend of mine is a retired Surveillance Photographer for Special Branch in the UK.  He used an amazing assortment of kit for his work from sub-miniature Minox cameras which fitted into a cigarette packet and allowed for a number of real cigs too (the lens was hidden in the pack logo!) to 1200mm lenses on 35mm camera bodies (was Nikon at the time  :( ) when working from a hide (often a van or truck left parked some hours earlier with my friend left inside for many hours with a tripod, sandwiches and two bottles; one with water, the other empty.
His advice would be NEVER mix up the bottles!  ;D

Hi, I've got a friend in law enforcement who is asking me for a recommendation for lens/camera combo for surveillance. I naturally thought to extend the question to you all!

What would you recommend as a set-up for surveillance? My friend won't be able to spend a ton of time learning the ins and outs of it and he's not interested in photography as an art. He will need to use it time to time at night and won't be using a flash (obviously).

Your thoughts?

P.S. Budget doesn't necessarily matter. Unless you are concerned about the fact that our taxes will be footing the bill... :)


The zeiss 1700 F/4 is a perfect canidate for surveillance, If you got the arms for it.  ;D

Anyone notice what camera kit Virgil uses in Homeland? He always gets the perfect shot of his target's face, and it looks like a light setup.

It's magic movie fairy dust. Can't you see the sparklies in the air whenever he uses it?

The 7D + 100-400 seems like a good starting point, or a 70-200 f/2.8 if he needs better low light but not as much focal length. He might not need as much as you'd think, he'll probably normally want to include multiple people and/or a fair bit of background of proof of where it was taken.

Either that or he can just use a 640x480 webcam and send if off to CSI for enhacement :D.

Since he's not interested in photography, why not just pick up the Canon PowerShot SX50 HS: http://www.bhphotovideo.com/c/product/889965-REG/Canon_PowerShot_SX50HS_Digital_Camera.html

50X optical zoom, 24-1200mm, 12.1MP, Full HD 1080p Video, Optical Image Stabilizer and High-Speed Burst HQ for 13fps Shooting.

That looks amazing.  And a small camera like that is very discrete.  I just wonder whether it would be any good at night?

That's the big question. Also a question of Auto-Focus. Contrast detect is very accurate, but tends to be slower and you may not be able to easily tell it what part you want in focus. I haven't read any reviews, so I don't know if that applies to this camera or not.

600D with a 600FD f4.5 and edmika adapter plus a kenko 1.4 teleconverter
 
in video mode with the 3x digital zoom you can film in HD at equivalent focal lengths of
960mm with normal
2880mm with the 3x digital zoom in video
and
1344mm with the TC and
4032mm if you turn on the 3x digital zoom and use the TC

All in HD and some big SD cards :D

definately gonna want a gimbal and sturdy tripod too

the reason i specify this lens is that its flat out unreal for video because the focus wheels are not on the lens so you can pull focus very gently without shaking the lens like you would with a ring focus of newer lenses
its also very sharp and 1/10th of the price of a new 600 f4L not that budget is the issue but the focus mechanism is much much better for video

but as for range and potential wide aperture this is killer
the 600 FD, gimal and the camera body can all be loaded into a pelican case 1510 with wheels and handle that fits in carry on baggage on a plane

you could also remote control the camera using an android tablet an OTG cable and the chainfire app to reduce shake.

This is a troll. No law enforcement officer will be asking us for information or advice.

Law enforcement agencies have experts in the field of survelience. There is gear availiable to them that is not offered up to the public, things like military grade night vision lenses, copies of the 1200 5.6 canon lens, and a host of other devices that would never appear on a public forum. Those in the know do not discuss these things in public.

If it isn't a troll, go talk to the FBI, or the RCMP, or whatever your national police force is. Posting in this forum is a very bad idea.

You guys are funny.  ;D You think Law Enforcement is like in the movies.  Unlimited budgets and computers that show you the fingerprints with cool noises as they check them.

If your friend is sitting in a parking lot, that means he needs something reasonable for the inside of a car ( a 5 year old american sedan with lousy shocks and brakes).  A crop DSLR and an 18-200 is probably where he wants to start. It is not unusual to shoot surveillance photos from 6 feet away, and the 18-200 gives tremendous range while easily handheld, and relatively inconspicuous.  A large aperture lens like a 70-200 f2.8 will add to the night shooting ability.

You HAVE to read some of the very creative comments on the amazon page for these...the first page or two kept me in stitches...
